CVE-2022-41948Network attack vector

Superuser escalation via privilege-chained user update

Published Dec 8, 2022 · Updated Apr 23, 2025

Privilege chaining in DHIS2 Core 2.34 through 2.39.0 allows remote authenticated users with user-admin authority to become superusers. The user update path accepts a crafted HTTP PUT that combines User and User Group management authorities without blocking self-assignment of superuser privileges. Exploitation requires authentication with user-admin authority and does not affect deployments where every user administrator is already a superuser.
